Question

viewership of the 24 - minute video was low, and you realize that people are more likely to review shorter videos of the food being prepared. you explored an article about the relationship between video length and views, which claims that the equation ( v = 1000 - 0.5s ) can predict the number of viewers, ( v ), who will review an entire video that is ( s ) seconds long. how long should a video be, according to the equation, if you want 950 viewers to review it?
200 seconds
5 seconds
100 seconds
25 seconds

Explanation:

Step1: Substitute given v into equation

$950 = 1000 - 0.5s$

Step2: Rearrange to isolate term with s

$0.5s = 1000 - 950$

Step3: Calculate right-hand side value

$0.5s = 50$

Step4: Solve for s

$s = \frac{50}{0.5}$

Answer:

100 seconds
